Running ASA and ASDM using GNS3/Qemu

Finally got ASA and ASDM to work nicely with GNS3.
Here's my setup:

GNS3 v0.7
Qemu (The one that comes with GNS3 v0.7)
ASA 802-k8 (files needed for Qemu are: asa802-k8.initrd.gz & asa802-k8.kernel)
ASDM 6.0(2)
Fiddler (Instructions to configure it are here)

To get ASDM to connect with ASA, you must use Fiddler to intercept the HTTPS stream and modify it to correct some of Qemu's shortcomings.
Then set your JRE to use fiddler as proxy.
All instructions can be found in the lengthy discussion at hacki.at. Make sure to read pages 17,18,+

Save VLAN.DAT in GNS/Dynamips

You know when you boot your router, the flash: is not saved and the vlan.dat that is saved on it is lost.. To remedy this, use a vlan.dat saved in nvram:

SW0(config)# vtp file nvram:/vlan.dat
SW0#dir nvram:
Directory of nvram:/

  123  -rw-        1683                      startup-config
  124  ----           5                      private-config
    1  -rw-           0                      ifIndex-table
    2  -rw-         780                      vlan.dat

There, now all your vlan/vtp config will be saved..
